Add the heavy whipping cream to a mixing bowl with the sugar substitute and vanilla extract, and beat on high until soft peaks form.

Place 1/4 cup of low carb vanilla ice cream in the bottom of each glass or container for your parfait.

Add a layer of berries on top of the ice cream.

Smooth an even layer of the whipped cream mixture on top of the berries.

Sprinkle sliced almonds on the top of your parfait, and garnish with a few more fresh berries.
